He Guys!
Again now in a readable from....
I have an Ubuntu 16.04 machine (K4.4 and K4.11, btrfs-progs v4.5.2) running / on btrfs raid1 and for some
month (after i had to replace a / disk) super_numdevices and num_devices are out of sync peventing me to boot
Kernels newer than around 4.7 (afaik), where the kernels began the be more restictive on checking valid btrfs
disks.
I tried to remove the raid and converted to single with several balances after that so that there are no raid
chunks left.

But again newer kernels refuse to boot with tlling me: "BTRFS error.....: super_num_devices 2 missmatch
with num_devices 1 found here".
So the the two counters are alwasy off by one, dont matter what i try.
Question: how do i get thouse two counters in sync again so that my system acts again as expected?!
